Reference was to Chevrolet Service Bulletin #3 dated March 18, 1965 and 
signed by R. G. Jordan, Zone Service Manager. entitled "Excessive Fuel 
Consumption - 1965 Corvair with Rochester HV carburetor" and refers to page 
6M-4 fig 8 of the 65 shop manual. It also says that carbs produced after 
November had a correction applied.

Just remembered that someone (not me) on the list had tried many things to 
increase a substandard MPG and thought it might be relevant.

ps indications are that in the 100 miles I drove my newly acquired 66, it 
got about 17.5 MPG with the chokes stuck closed.
